Donald Trump files $5 million lawsuit against Bill Maher

Business mogul-turned-reality star Donald Trump has filed a $5 million lawsuit against comedian Bill Maher over a joke.

During a January appearance on “The Tonight Show with Jay Leno,” staunch Democrat Maher offered to donate $5 million to a charity of Republican Trump’s choice if he could prove his father wasn’t an orangutan.

He said, “The color of his hair and the color of an orange orangutan is (sic) the only two things in nature of the same color.”

Unimpressed by the joke, “The Apprentice” star accepted the challenge and promptly mailed Maher a copy of his official birth certificate, and now he wants Maher to pay up.

The joke was a play on Trump’s relentless efforts to uncover facts about U.S. President Barack Obama’s heritage. Last year he promised to give $5 million to the politician’s favorite organization if he released his passport records and proved beyond doubt he’s an American citizen.
